Choose the FALSE statement:
A) Based on principles of artificial selection, dairy farmers should be able to change the genetic makeup of their livestock so that new generations evolve to produce more milk.
B) Based on a comparison of their structure, the wings of bats and dragonflies can be considered to be homologousstructures, and thus, products of divergent evolution.
C) Lyell and Hutton‘s observations that slow geological changes
gradually shaped the earth provided Darwin with the idea that
Nature could gradually determine the shape of life.
Multiple choice: Choose the
CORRECT statement as it relates to the
figures:
A) the two limb structures shown are examples of analogous structures.
B) the two limb structures shown are completely unrelated, and any resemblance between the two is merely coincidental.
C) the two limb structures shown are homologous to one another and provide evidence of common ancestry.
D) the two limb structures shown are an example of convergent evolution.
Multiple choice: Which of the following statements about pattern formation genes (e.g., the Hox genes) is CORRECT:
A) They provide a means of explaining how a mutation in a single gene can result in significant evolutionary changes, including the rapid appearance of complex structures.
B) An understanding of how these genes operate helps us explain punctuated equilibrium eliminates the notion that the fossil record should contain innumerable numbers of transitional forms.
C) Our understanding of these genes confirms that microevolutionary principles can be applied equally to account for micro- and macroevolutionary changes.
D) a and b are correct
